# Expert Advice:

01 -
  • It feels like you're eating something fancy when really you just assembled three good things together.
  • No cooking means no steam, no cleanup drama, and you can make it while still in your work clothes.
  • The texture contrast between crisp cucumber and creamy avocado somehow never gets boring.
02 -
  • Don't assemble these more than a few minutes before eating, or the cucumber will start to weep and everything gets soggy—I learned this during a failed meal prep experiment on a Wednesday.
  • The avocado will brown if it sits exposed to air for too long, so mix it into the tuna filling right before you eat rather than prepping it in advance.
03 -
  • Choose cucumbers that are roughly the same diameter so they fill evenly and look intentional rather than haphazard.
  • The mustard is optional but genuinely transforms the flavor profile—don't skip it just because the amount seems tiny.
